FIELD OF THE INVENTION

The invention provides compounds, pharmaceutical compositions and methods of use of certain compounds that are antagonists of the chemokine receptor. The compounds are useful to modulate a medical condition that is mediated by chemokine receptor activity or signaling, such as diseases and disorders associated with reduced hematopoietic stem cell mobilization. The compounds can also be useful in the treatment or prevention of inflammation, the treatment or prevention of human immunodeficiency virus infections (HIV), or the diagnosis, prevention, and treatment of cancer or cancer related pathologies and side effects.

BACKGROUND

Chemokines are considered to be principal mediators in the initiation and maintenance of inflammation. This superfamily of small, secreted cytokines induce, through their interaction with G-protein-coupled receptors, cytoskeletal rearrangements and directional migration of several cell types (Butcher, et al. (1999) Adv Immunol 72: 209-253; Campbell and Butcher (2000) Curr Opin Immunol 12: 336-341; Zlotnik and Yoshie (2000) Immunity 12: 121-127). They have also been found to play an important role in the regulation of endothelial cell function, including proliferation, migration and differentiation during angiogenesis and re-endothelialization after injury (Gupta et al. (1998) J Biol Chem, 7:4282-4287).

The chemokine receptor, CXCR4, is known in viral research as a major coreceptor for the entry of T cell line-tropic HIV (Feng, et al. (1996) Science 272: 872-877; Davis, et al. (1997) J Exp Med 186: 1793-1798; Zaitseva, et al. (1997) Nat Med 3: 1369-1375; Sanchez, et al. (1997) J Biol Chem 272: 27529-27531). T Stromal cell derived factor 1 (SDF-1) is a naturally occurring chemokine that interacts specifically with CXCR4. When SDF-1 binds to CXCR4, CXCR4 activates Gα₁-protein-mediated signaling (pertussis toxin-sensitive) (Chen, et al. (1998) Mol Pharmacol 53: 177-181), including downstream kinase pathways such as Ras/MAP Kinases and phosphatidylinositol 3-kinase (PI₃K)/Akt in lymphocyte, megakaryocytes, and hematopoietic stem cells (Bleul, et al. (1996) Nature 382: 829-833; Deng, et al. (1997) Nature 388: 296-300; Kijowski, et al. (2001) Stem Cells 19: 453-466; Majka, et al. (2001) Folia. Histochem. Cytobiol. 39: 235-244; Sotsios, et al. (1999) J. Immunol. 163: 5954-5963; Vlahakis, et al. (2002) J. Immunol. 169: 5546-5554). In mice transplanted with human lymph nodes, SDF-1 induces CXCR4-positive cell migration into the transplanted lymph node (Blades et al. (2002) J. Immunol. 168: 4308-4317). These results imply that the interaction between SDF-1 and CXCR4 directs cells to the organ sites with high levels of SDF-1.

Studies have shown that CXCR4 interactions may regulate the migration of metastatic cells. Hypoxia, a reduction in partial oxygen pressure, is a microenvironmental change that occurs in most solid tumors and is a major inducer of tumor angiogenesis and therapeutic resistance. Hypoxia increases CXCR4 levels (Staller, et al. (2003) Nature 425: 307-311). Microarray analysis on a sub-population of cells from a bone metastatic model with elevated metastatic activity showed that one of the genes increased in the metastatic phenotype was CXCR4. Furthermore, overexpression of CXCR4 in isolated cells significantly increased the metastatic activity (Kang, et al. (2003) Cancer Cell 3: 537-549). In samples collected from various breast cancer patients, Muller et al. (Muller, et al. (2001) Nature 410: 50-56) found that CXCR4 expression level is higher in primary tumors relative to normal mammary gland or epithelial cells. These results suggest that the expression of CXCR4 on cancer cell surfaces may direct the cancer cells to sites that express high levels of SDF-I. Consistent with this hypothesis, SDF-1 is highly expressed in the most common destinations of breast cancer metastasis including lymph nodes, lung, liver, and bone marrow. Moreover, CXCR4 antibody treatment has been shown to inhibit metastasis to regional lymph nodes when compared to control isotypes that all metastasized to lymph nodes and lungs (Muller, et al. (2001)).

In addition to regulating migration of cancer cells, CXCR4-SDF-1 interactions may regulate vascularization necessary for metastasis. Blocking either CXCR4/SDF-1 interaction or the Gα₁ signaling inhibits VEGF-dependent neovascularization. These results indicate that SDF-1/CXCR4 controls signaling systems that are regulators of endothelial cell morphogenesis and angiogenesis. Numerous studies have shown that VEGF and MMPs actively contribute to cancer progression and metastasis.

Cancer is currently the second leading cause of death in developed nations. In 2008, the American Cancer Society estimated that approximately 1.43 million new cases were diagnosed in the U.S. alone, and approximately 565,000 deaths occurred due to cancer (American Cancer Society, Cancer Facts & Figures 2008). Metastasis, the spread and growth of tumor cells to distant organs, is the most devastating attribute of cancer. Most morbidity and mortality associated with certain types of cancer, such as breast cancer, is associated with disease caused by metastatic cells rather than by the primary tumor. Therapy for metastasis currently relies on a combination of early diagnosis and aggressive treatment of the primary tumor.

The establishment and growth of metastases at distant sites is thought to depend on interactions between tumor cells and the host environment. Although a number of mediators have been implicated in the metastasis of cancers such as breast cancer, the precise mechanisms determining the directional migration and invasion of tumor cells into specific organs remain to be established. An incomplete understanding of the molecular and cellular mechanisms underlying metastasis has hindered the development of effective therapies that would eliminate or ameliorate this condition.

Several strategies have been developed to reduce metastatic invasion of malignant cells by regulating adhesion of endothelial cells with antibodies or adhesion molecules (see for example, PCT Publication No. WO 97/00956, U.S. Pat. Nos. 5,993,817; 6,433,149; 6,475,488; and 6,358,915). However, no commercial strategy has provided an effective treatment to prevent metastasis.

As of the end of 2007, an estimated 33 million people worldwide were living with HIV/AIDS, and the Centers for Disease Control and Prevention (CDC) estimate that 1,200,000 U.S. residents are living with HIV infection (UNAIDS/WHO AIDS epidemic update, December 2008; The Henry J. Kaiser Family Foundation HIV/AIDS Policy Fact Sheet, July 2007). Although new infections have decreased in recent years, an estimated 2.6 million new HIV infections occurred worldwide during 2007 and approximately 40,000 new HIV infections occur each year in the United States.

HIV entry within the target cells involves a series of molecular events. The three main steps of virus entry within the cell are: (i) attachment of the virus to the host cells; (ii) interaction of the virus with the co-receptors; (iii) fusion of the virus and host cell membranes. Considering the complexity of the molecular events involved in viral infection, all three of these steps have been considered for the drug design of HIV entry inhibitors. The T-lymphocyte cell surface protein CD4 is the primary receptor involved in the interaction with the viral glycoprotein gp120, but a cellular co-receptor is also needed for the successful entry of the virus within the cell. At least two types of such co-receptors have been identified so far, both of which are chemokine receptors. These chemokine receptors are therefore gateways for HIV entry, determinants of viral tropism and sensitivity.

Compounds targeting CXCR4 have been developed primarily for treatment of HIV because CXCR4 is a major coreceptor for T-tropic HIV infection. For example, U.S. Pat. No. 6,429,308 to Hisamitsu Pharmaceutical Co., Inc. discloses an antisense oligonucleotide to CXCR4 to inhibit the expression of the CXCR4 protein for use as an anti-HIV agent. PCT Publication No. WO 01/56591 to Thomas Jefferson University describes peptide fragments of viral macrophage inflammatory protein II which are described as selectively preventing CXCR4 signal transduction and coreceptor function in mediating entry of HIV-1.

Peptide antagonists of CXCR4 receptors have also been disclosed. Tamamura et al. (Tamamura, et al. (2000) Bioorg. Med. Chem. Leu. 10: 2633-2637; Tamamura, et al. (2001) Bioorg. Med. Chem. Leu. 11: 1897-1902) reported the identification of a specific peptide-based CXCR4 inhibitor, T140. T140 is a 14-residue peptide that possessed high levels of anti-HIV activity and antagonism of T cell line-tropic HIV-1 entry among all antagonists of CXCR4 (Tamamura, et al. (1998) Biochem. Biophys. Res. Commun. 253: 877-882). The compound has been altered to increase its efficacy and bioavailability by, for example, amidating the C-terminal of T-140 and reducing the total positive charges by substituting basic residues with nonbasic polar amino acids to generate TN14003, which is less cytotoxic and more stable in serum compared to T140. The concentration of TN14003 required for 50% protection of HIV-induced cytopathogenicity in MT-4 cells is 0.6 nM in contrast to 410 mM leading to 50% toxicity. U.S. Pat. No. 6,344,545 to Progenics Pharmaceuticals, Inc. describes methods for preventing HIV-1 infection of CD4+ cells with peptide fragments. U.S. Pat. No. 6,534,626 to the U.S. Department of Health & Human Services describes certain peptide chemokine variants for treating HIV infections. PCT Publication No. WO 04/087068 to Emory University describes CXCR4 peptide antagonists, particularly TN14003, and methods of their use to treat metastasis.

Other peptide-based antagonists have also been disclosed. For example, European Patent Publication Nos. 1286684 and 1061944 to the University of British Columbia cover methods of treatment of diseases, including metastasis, using modified peptide CXCR4 antagonists derived from the native SDF-1 ligand. PCT Publication No. WO 04/020462 to Takeda Chemical Industries, Ltd. provides peptide CXCR4 antagonists for treatment and prevention of breast cancer and chronic rheumatoid arthritis. U.S. Patent Application No. 2004/0132642 to the U.S. Dept. of Health & Human Services in part covers methods of inhibiting metastasis or growth of a tumor cell with a polypeptide CXCR4 inhibitor.

Several groups have now also identified chemokines including CXCR4 as a target for treatment of metastatic cancers. For example, PCT Publication Nos. WO 01/38352 to Schering Corporation, WO 04/059285 to Protein Design Labs, Inc., and WO 04/024178 to Burger generally describe methods of treating diseases and specifically inhibiting metastasis by blocking chemokine receptor signaling.

Although advances have been made, inadequate absorption, distribution, metabolism, excretion or toxicity properties of peptide inhibitors have limited their clinical use. Small non-peptide drugs remain a major goal of medicinal chemistry programs in this area.

At the present time, the metal-chelating cyclams and bicyclams represent one of the few reported non-peptide molecules to effectively block CXCR4 (Onuffer and Horuk (2002) Trends Pharmacol Sci 23: 459-467.36). One of these non-peptide molecules is AMD3100, which entered clinical trials as an anti-HIV drug that blocks CXCR4-mediated viral entry (Donzella, et al. (1998) Nat Med 4: 72-77; Hatse, et al. (2002) FEBS Lett 527: 255-262; Fujii, et al. (2003) Expert Opin Investig Drugs 12: 185-195; Schols, et al. (1997) Antiviral Res 35: 147-156).

However, a clinical study showed cardiac-related side effect of AMD3100 which in part caused its withdrawal from clinical development (Scozzafava, et al. (2002) J Enzyme Inhib Med Chem 17: 69-7641); Hendrix, et al. (2004) Journal of Acquired Immune Deficiency Syndromes 37(2)).

Other nitrogen containing bicyclic molecules have also been developed as CXCR4 antagonists. European Patent Publication No. 1431290 and PCT Publication No. WO 02/094261 to Kureha Chemical Industry Co., Ltd cover CXCR4 inhibitors that are potentially useful in treating various diseases including HIV infection.

U.S. Patent Publication No. 2004/0254221 to Yamamazi, et al. also provides compounds and use thereof to treat various diseases including HIV infections that are CXCR4 antagonists. The compounds are of the general Formula:

in which A is A₁-G₁-N(R₁)—; A₁ is hydrogen or an optionally substituted, mono- or polycyclic, heteroaromatic or aromatic ring; G₁ is a single bond or —C(R₂)(R₃)—; R₁, R₂, and R₃ can be optionally substituted hydrocarbon groups; W is an optionally substituted hydrocarbon or heterocyclic ring; x is —C(═O)NH—; y is —C(═O)—; and D₁ is hydrogen atom, alkyl with a polycyclic aromatic ring, or amine.

PCT Publication No. WO 00/56729 and U.S. Pat. No. 6,750,348 to AnorMED describe certain heterocyclic small molecule CXCR4 binding compounds, teaching that these are useful for the protection against HIV infection. The compounds are of the general Formula:

in which W can be a nitrogen or carbon atom; Y is absent or is hydrogen; R¹ to R⁷ can be hydrogen or straight, branched or cyclic C₁₋₆ alkyl; R⁸ is a substituted heterocyclic or aromatic group; Ar is an aromatic or heteroaromatic ring; and X is specified ring structure.

PCT Publication No. WO 2004/091518 to AnorMED also describes certain substituted nitrogen containing compounds that bind to CXCR4 receptors. The compounds are described as having the effect of increasing progenitor cells and/or stem cells, enhancing production of white blood cells, and exhibiting antiviral properties. PCT Publication No. WO 2004/093817 to AnorMED also discloses substituted heterocyclic CXCR4 antagonists which are described as useful to alleviate inflammatory conditions and elevate progenitor cells, as well as white blood cell counts. Similarly, PCT Publication No. WO 2004/106493 to AnorMED describes heterocyclic compounds that bind to CXCR4 and CCR5 receptors consisting of a core nitrogen atom surrounded by three pendant groups, wherein two of the three pendant groups are preferably benzimidazolyl methyl and tetrahydroquinolyl, and the third pendant group contains nitrogen and optionally contains additional rings. The compounds demonstrate protective effects against infections of target cells by a human immunodeficiency virus (HIV).

PCT Patent Application PCT/US06/000604, filed Jan. 9, 2006, describes certain compounds for the treatment of medical disorders mediated by CXCR4. These compounds include two nitrogen linked cyclic substituents off a central aromatic or cyclic alkyl or heteroalkyl.

In light of the fact that chemokine receptors are implicated in metastatic signaling as well as a number of other pathogenic conditions, it is important to identify new effective chemokine receptor modulators.

It is therefore an object of the invention to provide new compounds, methods and compositions that modulate chemokine receptors.

It is another object of the invention to provide compounds, methods and compositions that bind to chemokine receptors and interfere with their binding to their native ligands.

It is also an object of the invention to provide new compounds, methods and compositions for the treatment of viral infection, such as HIV, as well as for treatment of inflammatory and proliferative disorders.

DETAILED DESCRIPTION OF THE INVENTION

The compounds, methods, and compositions of the present invention can modulate the effect of chemokine receptors. These compounds can be used to treat diseases and disorders that are associated with CXCR4 activation, including diseases and disorders associated with reduced hematopoietic stem cell mobilization. In addition, methods of treatment of disorders including tumor metastasis or any other disease, particularly hyperproliferative diseases involving chemokine receptors are provided. The compounds can also be used to treat or prevent HIV infection, reduce viral load, or alleviate progression towards, or the symptoms of, AIDS in a host in need thereof.

Compounds described herein have the capacity to interact with chemokine receptors and potentially inhibit receptor signaling. The compounds of the present invention have increased bioavailability and efficacy in inhibiting chemokine receptors.

Although not bound by theory, these compounds may inhibit certain disorders such as metastasis through their capacity to inhibit SDF-1-chemokine receptor interactions, which can decrease cell targeting, and may also reduce VEGF-dependent endothelial cell morphogenesis and angiogenesis. This endothelial cell growth is a key event in metastases of tumors.

DEFINITIONS

The term “organism,” “host,” or “patient” are used interchangeably to refer to any living entity comprised of at least one cell. A living organism can be as simple as, for example, a single eukaryotic cell or as complex as a mammal, including a human being. In certain embodiments, the organism is a human in need of treatment.

The term “chemokine receptor modulator” means a substance including but not limited to a molecule, polypeptide, polynucleotide, inhibitory polynucleotide, or siRNA, that interferes or inhibits the biological activity of the chemokine receptors including, but not limited to, the binding of a ligand to the receptor. The term “chemokine peptide antagonist” means a polypeptide that specifically binds to a chemokine receptor, particularly polypeptides that are not an antibody. Representative chemokine peptide antagonists include T140 and derivatives of T140. Exemplary derivatives of T140 include, but are not limited to, TN14003, TC14012, and TE14011 as well as those found in Tamamura, H. et al. Org. Biomol. Chem. 1:3656-3662, 2003, which is incorporated by reference herein in its entirety.

The term “therapeutically effective amount” or “effective amount”, as used herein, means an amount of a compound or composition which is sufficient enough to significantly and positively modify the symptoms and/or conditions to be treated (e.g., provide a positive clinical response). The effective amount of an active ingredient for use in a pharmaceutical composition will vary with the particular condition being treated, the severity of the condition, the duration of the treatment, the nature of concurrent therapy, and the particular active ingredient(s) being employed, and like factors within the knowledge and expertise of the attending physician. For example, in reference to cancer or pathologies related to unregulated cell division, a therapeutically effective amount refers to that amount which has the effect of (1) reducing the size of a tumor, (2) inhibiting (that is, slowing to some extent, preferably stopping) aberrant cell division, for example cancer cell division, (3) preventing or reducing the metastasis of cancer cells, and/or, (4) relieving to some extent (or, preferably, eliminating) one or more symptoms associated with a pathology related to or caused in part by unregulated or aberrant cellular division, including for example, cancer, or angiogenesis. With respect to stem cell mobilization, an effective amount is sufficient to improve stem cell mobilization as measured, for example, by an increase in the presence of and/or activity of blood cell types including those of myeloid (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes/platelets, dendritic cells), and/or lymphoid lineages (T-cells, B-cells, NK-cells). Representative dosage ranges and administrative regimes are further described below, however these can be subject to adjustment in individual patients. A “pharmaceutical composition” refers to a mixture of one or more of the compounds described herein, or pharmaceutically acceptable salts thereof, with other chemical components, such as physiologically acceptable carriers and excipients. One purpose of a pharmaceutical composition is to facilitate administration of a compound to an organism.

As used herein, a “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” refers to a carrier or diluent that does not cause significant irritation to an organism and does not abrogate the biological activity and properties of the administered compound.

An “excipient” refers to an inert substance added to a pharmaceutical composition to further facilitate administration of a compound, such as binders, anti-adherents, coatings, disintegrants, fillers, diluents, flavors, colors, glidants, lubricants, preservatives, sorbitans, and sweeteners. Examples, without limitation, of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils and polyethylene glycols.

“Treating” or “treatment” of a disease includes preventing the disease from occurring in an animal that may be predisposed to the disease but does not yet experience or exhibit symptoms of the disease (prophylactic treatment), inhibiting the disease (slowing or arresting its development), providing relief from the symptoms or side-effects of the disease (including palliative treatment), and relieving the disease (causing regression of the disease). With regard to HIV or cancer, these terms can mean that the life expectancy of an individual affected with HIV or cancer will be increased or that one or more of the symptoms of the disease will be reduced.

The term “prodrug” refers to an agent, including nucleic acids and polypeptides, which is converted into a biologically active form in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent compound. They may, for instance, be bioavailable by oral administration whereas the parent compound is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. A prodrug may be converted into the parent drug by various mechanisms, including enzymatic processes and metabolic hydrolysis. Harper, N.J. (1962). Drug Latentiation in Jucker, ed.

Methods of Treatment

The compounds described herein, are particularly useful for the treatment or prevention of a disorder associated with chemokine receptor binding or activation. The methods of treatment or prevention of diseases or disorders herein by administration of a compound as described herein may alternatively be a method of use of the compounds for treatment or prevention of the diseases or disorders, or may be a method of use of the compound in the manufacture of a medicament for treatment or prevention of the disease or disorder in a host. In certain embodiments, the host is a human, an in particular, a human in need of chemokine receptor inhibition. In certain embodiments, the host in need is at risk of suffering from a disorder causing a reduction in lymphocytes or myeloid cells.

Generally, the disclosure provides compositions and methods for treating or preventing a chemokine receptor mediated pathology by administering a compound of the present invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof to a host in a therapeutic amount, for example in an amount sufficient to inhibit chemokine signal transduction in a cell expressing a chemokine receptor or homologue thereof.

In certain embodiments, the compounds are useful for treating disorders associated with reduced hematopoetic stem cell mobilization. The interaction between SDF-1 and CXCR4 is important in hematopoietic stem cell homing to the bone marrow and in hematopoietic stem cell quiescence. Hematopoietic stem cells can be mobilized into all blood cell types including myeloid (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes/platelets, dendritic cells), and lymphoid lineages (T-cells, B-cells, NK-cells).

Because the interaction between SDF-1 and CXCR4 plays an important role in holding hematopoietic stem cells in the bone marrow, the compounds described herein that are CXCR4 antagonist compounds are capable of “mobilizing” hematopoietic stem cells into the bloodstream as peripheral blood stem cells. Peripheral blood stem cell mobilization is very important in hematopoietic stem cell transplantation (an alternative to transplantation of surgically-harvested bone marrow) and is currently performed using drugs such as G-CSF.

In some embodiments, the compounds can be useful for affecting disorders that are associated with a disorder causing a hormone fluctuation or affecting the autonomic nervous system. In particular, such disorders can affect sensations involving temperature, such as hot flashes, cause dizziness or lightheadedness, or have similar somatosensory affects.

Another embodiment provides uses of a compound of the present invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof for the treatment of, or for the manufacture of a medicament for the treatment of chemokine receptor mediated pathologies including, but not limited to cancer or inflammation. Still another embodiment provides uses of a chemokine peptide antagonist for the manufacture of medicament for the prevention of tumor cell metastasis in a mammal

In a separate embodiment, a method for treating diseases of vasculature, inflammatory and degenerative diseases is provided including administering a compound of Formula (I)-(V) to a host. In one embodiment, a compound of Formula (I)-(V) is used to stimulate the production and proliferation of stem cells and progenitor cells.

In a separate embodiment, a method for the treatment of, prevention of, or reduced severity of inflammatory disease states, neovascularization, and wound healing including administering at least one compound described herein is provided.

Vascular endothelial cells express a multitude of chemokine receptors, with CXCR4 being particularly prominent (Gupta, et al. (1998) J Biol Ghem. 273: 4282; Volin, et al. (1998) Biochem Biophys Res ommnun. 242: 46). A RT-PCR based strategy which utilized CXCR4 specific primers demonstrated that mRNA for the chemokine receptor CXCR4 is expressed not only in primary culturs and transformed type II alveolar epithelial cells (pneumocytes) but also in a number of epithelial cell lines derived from various other tissues. (Murdoch, et al. (1998) Immunology. 98(1): 36-41). Unlike with endothelial cells, CXCR4 is the only chemokine receptor expressed on epithelial cells. The receptor may have a functional role in epithelial pathology. Whether CXCR4 participates in inflammatory responses remains unclear. CXCR4 expressed on the epithelium may facilitate the recruitment of phagocytic cells to sites of inflammation by direct effects on epithelial cells. CXCR4 may also have other functional roles within the immune response or participate in wound healing or neovascularization. CXCR4 may also be involved in the pathophysiology of several acute or chronic inflammatory disease states associated with the epithelium. (Murdoch, et al. (1999) Immunology. 98(1): 36-41).

In addition, the invention is directed to methods of treating animal subjects, in particular, veterinary and human subjects, to enhance or elevate the number of progenitor cells and/or stem cells. The progenitor and/or stem cells may be harvested and used in cell transplantation. In one embodiment, bone marrow progenitor and/or stem cells are mobilized for myocardial repair. Further, the invention is directed to methods of treating animal subjects, in particular, veterinary and human patients, who are defective in white blood cell (WBC) count, or who would benefit from elevation of WBC levels using the compounds disclosed herein. Moreover, the invention is directed to methods of effecting regeneration of cardiac tissue in a subject in need of such regeneration using the disclosed compounds.

The compounds of the invention may be used for the treatment of diseases that are associated with immunosuppression such as individuals undergoing chemotherapy, radiation therapy, enhanced wound healing and burn treatment, therapy for autoimmune disease or other drug therapy (e.g. corticosteroid therapy) or combination of conventional drugs used in the treatment of autoimmune diseases and graft transplantation rejection, which causes immunosuppression; immunosuppression due to congenital deficiency in receptor function or other causes; and infectious diseases, such as parasitic diseases, including but not limited to helminth infections, such as nematodes. The method of the invention thus targets a broad spectrum of conditions for which elevation of progenitor cells and/or stem cells in a subject would be beneficial or, where harvesting of progenitor cells and/or stem cell for subsequent stem cell transplantation would be beneficial. In addition, the method of the invention targets a broad spectrum of conditions characterized by a deficiency in white blood cell count, or which would benefit from elevation of said white blood cell count.

The term “progenitor cells” refers to cells that, in response to certain stimuli, can form differentiated hematopoietic or myeloid cells. The presence of progenitor cells can be assessed by the ability of the cells in a sample to form colony-forming units of various types, including, for example, CFU-GM (colony-forming units, granulocytemacrophage); CFU-GEMM (colony-forming units, -multipotential); BFU-E (burst-forming units, erythroid); HPP-CFC (high proliferative potential colony-forming cells); or other types of differentiated colonies which can be obtained in culture using known protocols. “Stem” cells are less differentiated forms of progenitor cells. Typically, such cells are often positive for CD34. Some stem cells do not contain this marker, however. In general, CD34+ cells are present only in low levels in the blood, but are present in large numbers in bone marrow.

The compounds of the invention may be administered as sole active ingredients, as mixtures of various compounds of Formula (I)-(V), and/or in admixture with additional active ingredients that are therapeutically or nutritionally useful, such as antibiotics, vitamins, herbal extracts, anti-inflammatories, glucose, antipyretics, analgesics, granulocyte-macrophage colony stimulating factor (GM-CSF), Interleukin-1 (IL-i), Interleukin-3 (IL-3), Interleukin-8 (IL-8), PIXY-32 1 (GM-CSF/IL-3 fusion protein), macrophage inflammatory protein, stem cell factor, thrombopoictin, growth related oncogene or chemotherapy and the like. In addition, the compounds of the invention may be administered in admixture with additional active ingredients that are therapeutically or nutritionally useful, such as antibiotics, vitamins, herbal extracts, anti-inflammatories, glucose, antipyretics, analgesics, and the like.

The binding of SDF-1 to CXCR4 has also been implicated in the pathogenesis of atherosclerosis (Abi-Younes et al. Circ. Res. 86, 131-138 (2000)), renal allograft rejection (Either et al. Transplantation 66, 1551-1557 (1998)), asthma and allergic airway inflammation (Yssel et al. Clinical and Experimental Aller 28, 104-109 (1998); JBC vol. 164, 59355943 (2000); Gonzalo et al. J. Immunol. 165, 499-508 (2000)), Alzheimer's disease (Xia et al. J. Neurovirology 5, 32-41 (1999)) and Arthritis (Nanici et al. J. Immunol. 164, 5010-5014 (2000)).

In one particular embodiment, a method of preventing metastasis of a malignant cell is provided that includes contacting the cells with a compound of Formula I-V, or a pharmaceutically acceptable salt, ester or prodrug thereof. In a separate embodiment, a method of treating proliferative disorders by administering a compound of Formulas (I)-(V) to a host in need of treatment is provided.

In another embodiment, the invention provides a method of reducing neovascularization, particularly VEGF-dependent neocascularization, by contacting a cell with a compound of Formula (I)-(V). The cell can be in a host animal.

In a separate embodiment, a method for treating diseases of vasculature, inflammatory and degenerative diseases is provided including administering a compound of Formula (I)-(V) to a host. In one embodiment, a compound of Formula (I)-(V) is used to stimulate the production and proliferation of stem cells and progenitor cells.

The compounds can prevent or reduce the severity of diseases associated with CXCR4 activity, and in particular of proliferative diseases in any host. However, typically the host is a mammal and more typically is a human. In certain subembodiments the host has been diagnosed with a hyperproliferative disorder prior to administration of the compound, however in other embodiments, the host is merely considered at risk of suffering from such a disorder.

Host, including humans suffering from, or at risk for, a proliferative disorder can be treated by administering an effective amount of a pharmaceutical composition of the active compound.

Abnormal cellular proliferation, notably hyperproliferation, can occur as a result of a wide variety of factors, including genetic mutation, infection, exposure to toxins, autoimmune disorders, and benign or malignant tumor induction.

There are a number of skin disorders associated with cellular hyperproliferation. Psoriasis, for example, is a benign disease of human skin generally characterized by plaques covered by thickened scales. The disease is caused by increased proliferation of epidermal cells of unknown cause. In normal skin the time required for a cell to move from the basal layer to the upper granular layer is about five weeks. In psoriasis, this time is only 6 to 9 days, partially due to an increase in the number of proliferating cells and an increase in the proportion of cells which are dividing (G. Grove, mt. J. Dermatol. 18:111, 1979). Chronic eczema is also associated with significant hyperproliferation of the epidermis. Other diseases caused by hyperproliferation of skin cells include atopic dermatitis, lichen planus, warts, pemphigus vulgaris, actinic keratosis, basal cell carcinoma and squamous cell carcinoma.

Other hyperproliferative cell disorders include blood vessel proliferation disorders, fibrotic disorders, autoimmune disorders, graft-versus-host rejection, tumors and cancers. Blood vessel proliferative disorders include angiogenic and vasculogenic disorders. Proliferation of smooth muscle cells in the course of development of plaques in vascular tissue cause, for example, restenosis, retinopathies and atherosclerosis. The advanced lesions of atherosclerosis result from an excessive inflammatory-proliferative response to an insult to the endothelium and smooth muscle of the artery wall (Ross, R. Nature, 1993, 362:801-809) Both cell migration and cell proliferation play a role in the formation of atherosclerotic lesions.

Fibrotic disorders are often due to the abnormal formation of an extracellular matrix. Examples of fibrotic disorders include hepatic cirrhosis and mesangial proliferative cell disorders. Hepatic cirrhosis is characterized by the increase in extracellular matrix constituents resulting in the formation of a hepatic scar. Hepatic cirrhosis can cause diseases such as cirrhosis of the liver. An increased extracellular matrix resulting in a hepatic scar can also be caused by viral infection such as hepatitis. Lipocytes appear to play a major role in hepatic cirrhosis.

Mesangial disorders are brought about by abnormal proliferation of msangial cells. Mesangial hyperproliferative cell disorders include various human renal diseases, such as glomerulonephritis, diabetic nephropathy, malignant nephrosclerosis, thrombotic micro-angiopathy syndromes, transplant rejection, and glomerulopathies.

Another disease with a proliferative component is rheumatoid arthritis. Rheumatoid arthritis is generally considered an autoimmune disease that is thought to be associated with activity of autoreactive T cells (See, e.g., Harris, B. D., Jr. (1990) The New England Journal of Medicine, 322:1277-1289), and to be caused by autoantibodies produced against collagen and IgE.

Other disorders that can include an abnormal cellular proliferative component include Behcet's syndrome, acute respiratory distress syndrome (ARDS), ischemic heart disease, post-dialysis syndrome, leukemia, acquired immune deficiency syndrome, vasculitis, lipid histiocytosis, septic shock and inflammation in general.

Examples of proliferative disorders which can be the primary tumor that is treated, or which can be the site from which metastasis is inhibited or reduced, include but are not limited to neoplasms located in the: colon, abdomen, bone, breast, digestive system, liver, pancreas, peritoneum, endocrine glands (adrenal, parathyroid, pituitary, testicles, ovary, thymus, thyroid), eye, head and neck, nervous (central and peripheral), lymphatic system, pelvis, skin, soft tissue, spleen, thorax, and urogenital tract.

CXCR4 plays a crucial role in ocular diseases involving the retina such as age-related macular degeneration (ARMD). The retinal pigment epithelium has a major role in the physiological renewal of photoreceptor outer segments in the provision of a transport and storage system or nutrients essential to the photoreceptor layer. The retinal pigment epithelial (RPE) cells predominantly express CXCR4 receptors. (Crane, et al. (2000) J. Immunol. 165: 4372-4278). CXCR4 receptor expression on human retinal pigment epithelial cells from the blood-retina barrier leads to chemokine secretion and migration in response to stromal cell-derived factor 1a. J. limmunol. 200; 165: 4372-4278). The level of CXCR4 mRNA expression increases upon stimulation with IL-i 3 or TNFa (Dwinell, et al. (1999) Gastroenterology. 117: 359-367). RPE cells also migrated in response to SDF-1a indicating that SDF-1a/CXCR4 interactions may modulate the affects of chronic inflammation and subretinal neovascularization at the RPE site of the blood-retina barrier. (Crane I J, Wallace C A, McKillop-Smith S, Forrester N. CXCR4 receptor expression on human retinal pigment epithelial cells from the blood-retina barrier leads to chemokine secretion and migration in response to stromal cellderived factor 1a J. Immunol. 200; 165: 4372-4278).

Age-related macular degeneration is characterized by both primary and secondary damage of macular RPE cells. Early stages of ARMD are characterized by macular drusen, and irregular proliferation and atrophy of the RPE. The late stages of ARMD present with geographic RPE atrophy, RPE detachment and rupture, choroidal neovascularaization and fibrovascular disciform scarring. Common first symptoms include metamorphopisia and/or general central vision loss resulting in reading disability and difficulties in detecting faces. Late stages of ARMD cause central scomota, which is extremely disabling if occurrence is bilateral (Bressler and Bressler (1995) Ophthalmology. 1995; 102: 1206-1211).

The compounds, or pharmaceutically acceptable salts, solvates, prodrugs, or esters thereof of the present invention described herein can be used to treat or prevent cancer, in particular the spread of cancer within an organism. Cancer is a general term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissues and can spread through the bloodstream and lymphatic system to other parks of the body. It has been discovered that the administration of a chemokine receptor antagonist to a host, for example a mammal, inhibits or reduces the metastasis of tumor cells, in particular breast cancer and prostate cancer.

There are several main types of cancer, and the disclosed compounds or compositions can be used to treat any type of cancer. For example, carcinoma is cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.

Leukemia is cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the bloodstream. Lymphoma is cancer that begins in the cells of the immune system.

When normal cells lose their ability to behave as a specified, controlled and coordinated unit, a tumor is formed. A solid tumor is an abnormal mass of tissue that usually does not contain cysts or liquid areas. A single tumor may even have different populations of cells within it with differing processes that have gone awry. Solid tumors may be benign (not cancerous), or malignant (cancerous). Different types of solid tumors are named for the type of cells that form them. Examples of solid tumors are sarcomas, carcinomas, and lymphomas. Leukemias (cancers of the blood) generally do not form solid tumors. The compositions described herein can be used to reduce, inhibit, or diminish the proliferation of tumor cells, and thereby assist in reducing the size of a tumor.

Representative cancers that may treated with the disclosed compositions and methods include, but are not limited to, bladder cancer, breast cancer, colorectal cancer, endometrial cancer, head & neck cancer, leukemia, lung cancer, lymphoma, melanoma, non-small-cell lung cancer, ovarian cancer, prostate cancer, testicular cancer, uterine cancer, cervical cancer, thyroid cancer, gastric cancer, brain stem glioma, cerebellar astrocytoma, cerebral astrocytoma, ependymoma, Ewing's sarcoma family of tumors, germ cell tumor, extracranial cancer, Hodgkin's disease, leukemia, acute lymphoblastic leukemia, acute myeloid leukemia, liver cancer, medulloblastoma, neuroblastoma, brain tumors generally, non-Hodgkin's lymphoma, ostessarcoma, malignant fibrous histiocytoma of bone, retinoblastoma, rhabdomyosarcoma, soft tissue sarcomas generally, supratentorial primitive neuroectodermal and pineal tumors, visual pathway and hypothalamic glioma, Wilms' tumor, acute lymphocytic leukemia, adult acute myeloid leukemia, adult non-Hodgkin's lymphoma, chronic lymphocytic leukemia, chronic myeloid leukemia, esophageal cancer, hairy cell leukemia, kidney cancer, multiple myeloma, oral cancer, pancreatic cancer, primary central nervous system lymphoma, skin cancer, small-cell lung cancer, among others.

A tumor can be classified as malignant or benign. In both cases, there is an abnormal aggregation and proliferation of cells. In the case of a malignant tumor, these cells behave more aggressively, acquiring properties of increased invasiveness.

Ultimately, the tumor cells may even gain the ability to break away from the microscopic environment in which they originated, spread to another area of the body (with a very different environment, not normally conducive to their growth) and continue their rapid growth and division in this new location. This is called metastasis. Once malignant cells have metastasized, achieving cure is more difficult.

Benign tumors have less of a tendency to invade and are less likely to metastasize. They do divide in an uncontrolled manner, though. Depending on their location, they can be just as life threatening as malignant lesions. An example of this would be a benign tumor in the brain, which can grow and occupy space within the skull, leading to increased pressure on the brain. The compositions provided herein can be used to treat benign or malignant tumors.

In certain embodiments, the compounds described herein are useful for the treatment of HIV or AIDS in a host in need thereof.

In one embodiment, a method of treating or preventing HIV infection or reduction of symptoms associated with AIDS is provided including administering a compound of at least one of Formula (I)-(V) to a host. In certain embodiments, the compound can be provided to a host before treatment of infection with another compound. In a separate embodiment, the compound is provided to a patient that has been treated for HIV infection to reduce the likelihood of recurrence, or reduce mortality associated with AIDS related symptoms. In another embodiment, the compound is administered to a host at high risk of suffering from HIV infections.

Human and simian immunodeficiency viruses (HIV and SIV, respectively) enter cells through a fusion reaction triggered by the viral envelope glycoprotein (Env) and two cellular molecules: CD4 and a chemokine receptor, generally either CCR5 or CXCR5. (Alkhatib G, Combadiere C, Croder C, Feng Y, Kennedy P E, Murphy P M, Berger E A. CC CKR5. a RANTES, MIP-1alpha, MIP-1Beta receptor as a fusion cofactor for macrophage-tropic HIV-1. Science. 1996; 272: 1955-1988).

In approximately 50% of infected individuals, CXCR4-tropic (X4-tropic) viruses emerge later in HIV infection, and their appearance correlates with a more rapid CD4 decline and a faster progression to AIDS (Connor, et al. (1997) J Exp. Med. 185: 621-628). Dualtropic isolates that are able to use both CCR5 and CXCR4 are also seen and may represent intermediates in the switch from CCR5 to CXCR4 tropism (Doranz, et al. (1996) Cell. 85: 1149-1158).

Hosts, including humans suffering from, or at risk for, HIV infection can be treated by administering an effective amount of the active compound or a pharmaceutically acceptable prodrug or salt thereof in the presence of a pharmaceutically acceptable carrier or diluent.

The administration can be prophylactically for the prevention of HIV infection or reduction of symptoms associated with AIDS. The active materials can be administered by any appropriate route, for example, orally, parenterally, intravenously, intradermally, subcutaneously, or topically, in liquid or solid form. However, the compounds are particularly suited to oral delivery.

In a separate embodiment, a method for the treatment or prevention of HIV infection or reduction of symptoms associated with AIDS by administering a compound of the present invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof to a host in need of treatment is provided. The compounds of the invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof can be administered to a host in need thereof to reduce the severity of AIDS related disorders. In one embodiment of the invention, the host is a human.

In a separate embodiment, a method for the treatment of, prevention of, or reduced severity of liver disease associated with viral infections including administering at least one compound described herein is provided.

Chronic hepatitis C virus (HCV) and hepatitis B virus (HBC) infection is accompanied by inflammation and fibrosis eventually leading to cirrhosis. A study testing the expression and function of CXCR4 on liver-infiltrating lymphocytes (LIL) revealed an important role for the CXCL12/CXCR4 pathway in recruitment and retention of immune cells in the liver during chronic HCV and HBV infection (Wald, et al. (2004) European Journal of Immunology. 34(4): 1164-1174). High levels of CXCR4 and TGFβ have been detected in liver samples obtained from patients infected with HCV. (Mitra, et al. (1999) Int. J. Oncol. 14: 917-925). In vitro, TGF-β has been shown to up-regulate the expression of CXCR4 on naïve T cells and to increase their migration. The CD69/TGFβ/CXCR4 pathway may be involved in the retention of recently activated lymphocytes in the liver (Wald, et al. European Journal of Immunology. 2004; 34(4): 1164-1174).

In another embodiment, the invention provides a method of treating symptoms associated with other infections associated with chemokine receptor activation, for example, liver diseases associated with flavivirus or pestivirus infection, and in particular, HCV or HBV, by contacting a cell with a compound of the present invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof. The cell can be in a host animal, in particular in a human.

The compounds can treat or prevent HIV infection, or reduce the severity of AIDS related symptoms and diseases in any host. However, typically the host is a mammal and more typically is a human. In certain embodiments the host has been diagnosed with AIDS prior to administration of the compound, however in other embodiments, the host is merely infected with HIV and asymptomatic.

An exemplary dose of the compound will be in the range from about 1 to 50 mg/kg, preferably 1 to 20 mg/kg, of body weight per day, more generally 0.1 to about 100 mg per kilogram body weight of the recipient per day. The effective dosage range of the pharmaceutically acceptable salts and prodrugs can be calculated based on the weight of the parent compound to be delivered. If the salt, ester or prodrug exhibits activity in itself, the effective dosage can be estimated as above using the weight of the salt, ester, solvate, or prodrug, or by other means known to those skilled in the art.

The amount and frequency of administration of the compounds of the invention and/or the pharmaceutically acceptable salts thereof will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as the condition and/or severity of the symptoms being treated. A typical recommended daily dosage regimen for oral administration can range from about 0.1 mg/day to about 2000 mg/day, in one to four divided doses.

Pharmaceutical Compositions

In one embodiment, pharmaceutical compositions including at least one compound of the present invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof is provided.

The compound of the present invention, or a pharmaceutically acceptable salt, solvate, prodrug, or ester thereof is conveniently administered in unit any suitable dosage form, including but not limited to one containing 7 to 3000 mg, preferably 70 to 1400 mg of active ingredient per unit dosage form. A oral dosage of 50-1000 mg is usually convenient. Ideally the active ingredient should be administered to achieve peak plasma concentrations of the active compound of from about 1 μM to 100 mM or from 0.2 to 700 μM, or about 1.0 to 10 μM.

The concentration of active compound in the drug composition will depend on absorption, inactivation, and excretion rates of the drug as well as other factors known to those of skill in the art. It is to be noted that dosage values will also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed composition. The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at varying intervals of time.

A preferred mode of administration of the active compound is oral. Oral compositions will generally include an inert diluent or an edible carrier. They may be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches or capsules. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition.

The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring. When the dosage unit form is a capsule, it can contain, in addition to material of the above type, a liquid carrier such as a fatty oil. In addition, dosage unit forms can contain various other materials which modify the physical form of the dosage unit, for example, coatings of sugar, shellac, or other enteric agents.

The compound can be administered as a component of an elixir, suspension, syrup, wafer, chewing gum or the like. A syrup may contain, in addition to the active compounds, sucrose as a sweetening agent and certain preservatives, dyes and colorings and flavors.

The compound or a pharmaceutically acceptable prodrug or salts thereof can also be mixed with other active materials that do not impair the desired action, or with materials that supplement the desired action, such as antibiotics, antifungals, anti-inflammatories, or antiviral compounds, or with additional chemotherapeutic agents. Solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. The parental preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.

In a preferred embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release Formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters and polylactic acid. Methods for preparation of such Formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation. If administered intravenously, preferred carriers are physiological saline or phosphate buffered saline (PBS).

In certain embodiments, the active is provided an aqueous solution. The active can be dissolved in, for example, water, PBS, or a similar intert liquid. Similarly, when in a solid form, the active can be provided in conjunction with an inert carrier. Typically, the inert carrier makes up the remained of any given volume of liquid or solid Formulation, ie up to 100%. When actives are combined, the ratio of the actives can vary from about 1:10.000 to about 1:1, however the ratio is more typically from about 1:1 to about 1:50, or more typically about 1:1 to about 1:10. Ratios can be measured either on a molar basis or by weight.

Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) are also preferred as pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811 (which is incorporated herein by reference in its entirety). For example, liposome Formulations may be prepared by dissolving appropriate lipid(s) (such as stearoyl phosphatidyl ethanolamine, stearoyl phosphatidyl choline, arachadoyl phosphatidyl choline, and cholesterol) in an inorganic solvent that is then evaporated, leaving behind a thin film of dried lipid on the surface of the container. An aqueous solution of the active compound or its monophosphate, diphosphate, and/or triphosphate derivatives is then introduced into the container. The container is then swirled by hand to free lipid material from the sides of the container and to disperse lipid aggregates, thereby forming the liposomal suspension.

Combination and Alternation Therapy

In one embodiment, the compounds described herein are administered in combination or alternation with another active compound.

In certain embodiments, at least a second active compound is administered in combination or alternation with the first compound.

The second active compound can be a chemotherapeutic agent, for example an agent active against a primary tumor. Hosts, including humans suffering from or at risk for a proliferative disorder can be treated by administering an effective amount of a pharmaceutical composition of the active compound. In particular embodiments, the compound is useful in disorders in which hematopoietic stem cell mobilization is desired, such as upon administration of a chemotherapeutic agent. In these embodiments, it may be beneficial to administer the compound described herein in combination or alternation with a chemotherapeutic agent to reduce side effects of chemotherapy.

In certain other embodiments, the second active compound can be an antiviral, particularly an agent active against a HIV and in a particular embodiment, active against HIV-1.

Assay Examples

Small molecule chemokine receptor modulation, agonism or antagonism, can be mediated by direct binding to the receptor affecting the signaling and chemotatic effects of the natural ligand for its receptor. In addition modulation can be obtained by interaction of the small molecule with effectors of the particular chemokine receptor pathway. Small molecules can also affect CXCR4 homodimerization (Rodriguez-Frade, et al., J. Cell. Biol. 1999; Mellado et al., Annual Review of Immunology 2001; Toth et al., J. Pharm. and Exp. Ther. 2004; Wang et al., Mol. Cancer. Ther. 2006), heterodimerization with CCR2 (Percherancier, et al. JBC 2005, Sohy et al. JBC 2007) or CCR5 (Babcock, et al., JBC 2003) or CXCR7 (Sierro et al., PNAS 2007), delta opioid receptor (DOR) (Pello et al European J of 1 mm. 2008, Hereld and Jin European J. of 1 mm. 2008) or a T cell receptor (Kumar et al., Immunity 2006). Modulation of the SDF-1/CXCR4 pathway can also be accomplished by targeting the GPR54/KISS receptor (Navenot et al., Cancer Res. 2005), cannabanoid receptor 2 (CB2R) (Coopman et al., International Immunopharmacology 2007), ZAP-70 tyrosine kinase (Ottoson et al, J Immunology 2001) or sphingosine 1-phosphate receptors (Yopp et al., J. Immunology 2005).

Example 28 Screening by Functional Calcium Mobilization Assay

Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37° C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay.

Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds. Approximately 45 min after the test compound was added, cells were challenged with SDF-1α at EC₈₀-EC₉₀ concentration and calcium mobilization measured using a Flex Station fluorescence imager. Full dose response curves were generated daily for SDF-1a to calculate IC₅₀ concentrations. The IC₅₀ values are reported. In cases, where one was not determined, a percent inhibition at the 1 μM concentration was extrapolated.

The compounds of the invention generally have an IC₅₀ value below 100 micromolar for inhibition of calcium mobilization induced by SDF-1a. Results for specified compounds are shown in the Table 7.

Example 29 Testing Inhibition of CXCR4 Pathway by Functional Morphological SDF-1a Induced Changes

This assay measures the change in impedance that occurs when cells are stimulated with SDF-1a. Changes in shape and cytoskeleton result in a change of impedance that is dependent on the activation of the CXCR4 receptor. This assay is contracted to MDS Pharma Services and performed as described in http://discovery.mdsps.com/Catalog/Services/Screening/CellKey/AssayDetails.aspx?id=7 (Assay 930070). Briefly, human HeLa cells expressing endogenous CXCR4 are grown in vitro and receptor activation in live cells is measured using cellular dielectric spectroscopy (CDS). EC₅₀ is defined as a greater than 50% change in cellular impedance relative to the EC₁₀₀ (10 nM SDF-1a) response. IC₅₀ is defined as a greater than 50% inhibition of the cellular impedance change induced by an EC₅₀ concentration of SDF-1a incubation at 30 minutes.

The compounds of the invention generally have an IC₅₀ value below 100,000 nM the cellular impedance change induced by an EC₅₀ concentration of SDF-1α incubation at 30 minutes. Results for specified compounds are shown in the Table 8.

Example 30 Test Compound Activity Against HIV Strains

A selected set of compounds are tested for their ability to inhibit the cellular entry of T-tropic HIV. The assay for this inhibition is carried out on a contractual basis at Monogram Biosciences, Inc. using their well established Phenoscreen™ assay. Briefly, HIV strains of interest are tagged with a luciferase indicator gene to create an appropriate test vector. The test vector is amplified through transfection and the resulting virus is incubated in the presence of target host cells where intracellular florescence activity then becomes a measure of infection. Amplified virus is exposed to target host cells in the presence of a range of test drug concentrations to determine IC₅₀ measurements of entry inhibition. A modification of this test is further reapplied as a novel drug assay used in partnership with a number of pharmaceutical companies to test the effectiveness of novel entry inhibitors that target specific chemokines. It can used to detect activity against T-tropic, M-tropic, and dual-tropic viruses and Monogram Biosciences has a large bank of over 10,000 different virus strains to ultimately asses the range of applicability of our chemokine modulators. Certain compounds are tested to establish efficacy in a number of viral strains.

The compounds of the invention generally have an IC₅₀ value for viral entry inhibition in the one of the above HIV viral strains of interest of less than or equal to 100 μM. For example, compounds A, B, Z, AB, AY, and BP have IC₅₀ values of less than or equal to 10 μm.

In addition, compounds are tested in an HIV replication assay carried out by Southern Research Institute. The primary assay screens compounds in a microtiter assay which measures the ability of selected compounds to inhibit HIV-induced cell killing as well as the toxicity of the test compounds to host cells. Quantitation is performed spectrophotometrically using the tetrazolium dye MTS (Cell Titer; Promega) which is converted to a soluble, colored formazan product by mitochondrial enzymes present in metabolically active cells at six days post-infection. The basic assay involves infection of CEM-SS cells with virus in the presence of the test compound. Data are analyzed using a statistical software program developed at Southern and efficacy and toxicity endpoints are determined, as well as selectivity indices. A follow-up assay is performed using in fresh human peripheral blood lymphocytes and monocyte-macrophages infected with low passage primary virus isolates. Blood is obtained from the American Red Cross (screened for HIV and HBV) and mononuclear cells are isolated by Ficoll-hypaque centrifugation. The following are given as examples (and should not be taken as an exhaustive list) of virus strains tested: 92UG029 (X4), 92UG046 (X4), 93UG065 (X4), CMU02 (X4), 91US005 (R5) and 92UG001 (dual X4/R5), the co-receptor used by each given strain is described in paranthesis.

The compounds of the invention generally have an IC₅₀ value for viral entry inhibition in the one of the above HIV viral strains of interest of less than or equal to 100 μM and an antiviral index>10.

For radioligand binding competition test of CXCR4 or CXCR7, the following components are mixed in the wells of a 96 well plate (Master Block, Greiner, 786201) up to 100 μL assay buffer (50 mM HEPES; 5 mM MgCl₂; 1 mM CaCl₂, 250 mM Sucrose, 100 mM NaCl and 0.5% BSA), compounds to be tested or 200-fold excess of cold ligand for non specific binding determination (SDF1-α R&D, 350-NS), radioligand [¹²⁵I]-SDF-1α (PKI NEX346, 2200 Ci/mmol, diluted in assay buffer to give 0.03 nM) and 1 μg membrane extracts. The plate is incubated during 30 min at 37° C. in a water bath, filtered over GF/B filters (presoaked in 0.5% PEI for 1 h at room temperature) with a Filtermate Harvester (Perkin Elmer), and washed 6 times with 0.5 mL of ice cold filtration buffer (50 mM HEPES; 5 mM MgCl₂; 1 mM CaCl₂, 250 mM Sucrose, 0.5 M NaCl and 0.5% BSA). Following addition of 50 μL of Microscint 20 (Packard), and incubation during 15 min. on an orbital shaker, the plates are counted with a TopCount™ for 1 min/well.

Example 33 Results of Functional Calcium Mobilization Assay, Cytotoxicity and hERG Binding Assessments for Selected Compounds

Functional calcium mobilization assay was conducted as described in Example 27.

Cytotoxicity of the compounds was assessed by the following assay. CCRF-CEM cells in media (RPMI 1640, 15% FBS, Pen/Strep., 1% non-essential amino acids) are incubated with various concentrations of test compound for 6 days undisturbed. Cell number relative to no compound controls is determined using either Serotec's “Alamar blue” per manufacturers protocol or Promega's “Cell Titer 96 Aqueous One Solution Cell Proliferation Assay” kit per manufacturers protocol. The number cells not surviving after test compound administration is determined for each concentration tested and the EC₅₀ (concentration of compound in which 50% of the cells survive) is determined

The in vitro effects of the selected compounds on the hERG (human ether-á-go-go-related gene) potassium channel current (a surrogate for IKr, the rapidly activating, delayed rectifier cardiac potassium current) expressed in mammalian cells were evaluated at room temperature using the PatchXpress 7000A (Molecular Devices), an automatic parallel patch clamp system. Each compound was evaluated at varying concentrations in duplicate up to 10 μM, and the duration of exposure to each test article concentration was 5 minutes. For select compounds, the IC₅₀ values for compounds were determined if the concentration in which 50% channel block was observed was <10 μM. For <50% channel block at the 10 μM concentration, an % inhibition at 10 μM is listed. All other compounds have an % inhibition and concentration listed.

A summary of the results is shown in Table 9.
